生产制造追溯系统-在线打印

前言

很久没有写博客了(大概有4个月的样子了吧)，从2015年8月份开始一直忙于公司的系统，直到2016年6月底全部上线；包含4个厂区，每个厂区都是上千人的规模，而负责搞这个项目的算上我只有2个人，说多了都是泪：

美工？没有

测试人员？没有

DBA？没有

架构师？没有

运维？继续没有

估计大家都没遇见过这样的工作吧？哈哈.

历经艰难、跟各个部门(IE、PE、生产、PMC、QA等)唇枪舌战、好在在6月底总算是全部上线，总算是一点欣慰，毕竟决定了接手这个项目，那就要用心去做，只有用心了才能做好。

吐槽完毕，下面开始说正事儿

********我是华丽的分割线************************************************

公司的系统上线之后，我也稍微可以缓口气了，加班稍微少了一点，一般到了下午6点半就能下班，所以我还是决定将2015年初整理的这套项目拿出来继续优化，该项目已Web模式为主、客户端模式为辅，互相结合使用；目前主要包含以下几个主要功能模块：

本文主要说一下打印的问题，在生产制造业中条码打印是非常频繁的，也是必不可少的；我曾经亲身经历过这么一件事情：生产线在进行包装的时候，打印了两张卡通标签，但是操作员在将卡通标签贴在盒子上的时候贴反了，也就是说标签上面的序列号与盒子里面装的实物完全对不上，为此在海关被拦截了，当时厂里派了QA、生产、货仓与IT一同去海关处解决这个问题，我刚好在其中，整个过程是非常繁琐的，为此公司高层也要求必须杜绝这种品质事件，故我们也是采用了"在线打印"的方式进行包装，并且只有QA才有标签重打的权限。

这个故事反应了生产线的真实现象，所以我这边采用如下方式完成打印：

     function PrintLabel(box) {
            var api = '<%=MTS.Utility.MtsTool.GetApi() %>';
            
            var lurl = api + "?type=3&action=get_carton_sn&carton_sn=" + box;
            $.ajax({ url: lurl,
                cache: false,
                dataType: "text",
                success: function (data) {
                    if (data == null || data == undefined) {
                        alert("");
                        return;
                    }
                    var arr = data.split("|");
                    if (arr[0] == "0") {
                        alert(arr[2]);
                        return;
                    }
                    var t = eval("(" + arr[2] + ")"); //                                                              
                    try {
                        var labelId = $("#hid_LabelId").val();
                        window.external.PrintLabel("", t.key, t.value, ",", labelId);

                    } catch (e) {

                    };
                }
            });
        }

以上代码是Web应用程序中的脚本，主要是通过API获取需要打印的数据，这里返回的是text类型，其实也可以返回Json格式的数据；用户完成包装之后系统会按照包装规则产生一个唯一的卡通箱号，那么这个箱号就作为API的参数 carton_sn= box传进去，根据该箱号返回真实的包装数据；然后通过window.external调用客户端的打印函数。

通过如下代码获取本地默认打印机：

 

  //获取默认打印机
            System.Drawing.Printing.PrintDocument pringdocument = new System.Drawing.Printing.PrintDocument();
            string pring_name = pringdocument.PrinterSettings.PrinterName;//打印机名

 

因为我这里的客户端程序就是对Web程式加壳了，通过这个客户端程序就可以方便的获取本地默认打印机，采用这种方式比在网页中安装 activex 控件要爽的多，谁用谁知道.

网页传过来的参数以键值对为标准：

  string[] keys = key.Split(splitKey.ToCharArray(), StringSplitOptions.None);
  string[] values = value.Split(splitKey.ToCharArray(), StringSplitOptions.None);

我这里调用BarTender进行打印，代码如下：

 format = (BarTender.FormatClass)engine.Formats.Open(filename);
 format.SetNamedSubStringValue(key, value);
 format.PrintSetup.Printer = printerName;
 BarTender.Messages msg = null;
 format.Print("0", false, 1, out msg);

 以下代码是Code 128格式的条码：

  1  public class Code128
  2     {
  3         private DataTable m_Code128 = new DataTable();
  4         private uint m_Height = 40;
  5         /// 

  6         /// 高度
  7         /// 
  8         public uint Height { get { return m_Height; } set { m_Height = value; } }
  9         private Font m_ValueFont = null;
 10         /// 

 11         /// 是否显示可见号码  如果为NULL不显示号码

这样一来，操作员手上没有多的条码，必须包装完成之后系统才会一对一的打印一份条码出来，完成一个产品的包装就贴一个条码，很大程度上面避免了条码混乱的问题.

已完成的部分功能

 

#1工单维护：这个一般都是由PMC完成的，PMC根据排期计划合理创建工单，如果企业上了SAP系统，也可以直接链接到SAP系统进行下载工单资料，这样就更方便了.

#2工单优先级：PMC在创建工单的时候会指定该信息，生产过程中系统会体现该信息，起到提示用户的目的，管理者可根据实际情况随时变更该信息。

#3工艺路线维护：工艺路线由 IE 完成，生产部根据 IE 制定的工艺路线进行生产，系统会检测每一个工序的通过情况，比如上一个工序没有做则不可以直接跳到下一个工序。

#4目检过站：操作扫描条码过站，必须按照 IE 制定的工艺路线进行，如果扫描的条码不在当前工序，则系统会提示当前条码的正确位置。

#5目检过站：系统会将不良品强制打入维修中心，在完成修理之前无法进行其它的操作。

 #6组装动态装配：系统支持动态配置装配规则，不同的工单采用不同的规则进行装配，每一个装配条码可独立配置条码规则，比如长度、前缀等信息，防止用户输入错误。

 #7FQC送检：系统采用 AQL 标准动态抽检，打破传统的抽检模式，由系统自动计算需要抽检的产品，同时也由系统自动根据 AQL 标准进行结果判定，有效帮助品质人员进行品质监控与管理。

 #8FQC抽检：生产方面将产品以批次单位送检至QC，系统提示QC需要抽检的产品序列号，QC针对需要抽检的产品检测并录入抽检结果，系统根据抽检情况按照 AQL 自动判定.

 

 

  #9包装规则：针对每个工单配置相应的包装规则，比如卡通箱容量、箱号长度、箱号前缀等信息，并上传卡通标签模板。

 

#10包装：包装规则配置完成之后，即可扫描条码进行包装了。

 

结束包装的时候，系统自动将标签打印出来.

 

 

#11不良品维修：生产过程中的不良都会被系统强制打入维修中心，必须经过修理之后才能进行其它工序。

#12不良预警：系统会自动监控指定生产线的不良情况，当不良情况达到了红色预警值，则触发警报，系统自动锁定当前生产线，由管理者分析不良原因并改善之后进行解除预警。

 

#13成品发货：成品发货过程中支持上传实物图片。

 #14品质异常报告：用户发起品质异常，由工程部分析原因并给出改善，由QA确认是否可行。

 #15部分报表：

 #16电子看板：

因为工作日需要上班，白天必须做公司的事情，所以只有每天晚上熬夜和周末来做这个项目，说真的还是有点累，如果您觉得文章过得去，还请多多支持，谢谢各位园友！！
